The UN is also intensifying support to the Haitian government in building sound water, sanitation and health systems.

UN Deputy Secretary-General, Amina Mohammed, said the new plan and the expression of contrition generated "considerable goodwill" in the Caribbean island.

"Now the United Nations must demonstrate its commitment to theimplementation of the New Approach or risk dissipating that goodwill, needlessly heightening the suffering of the people of Haiti and incurring further reputational damage to the Organization. Secretary-General António Guterres is strongly committed to taking forward the New Approach. However, he needs the full support of the Membership in order to do so. UN action requires Member State action. We cannot fail the people of Haiti at this critical moment. We cannot leave Haiti behind."

Earlier in February, Secretary-General António Guterres asked Member States to inform him if they intend to make voluntary contributions the implementation of the new plan to counter cholera.

So far, Ms Mohammed said, the UN has received US$2.7 million from seven Member States and US$17,000 from UN staff members and private donors.
